Just some more information gathered

Watch this video again of Lisbon finding Partridge. At the 2:46 mark you can see Partridge's left arm. There is no blood on it at all/ This can mean one of many things

a) RJ cut off his tattoo after attacking Lisbon

b) Someone in Tyger/Tyger cut it off so theri organization would stay secret. At this time no one knew of the tattoos.

c) Partridge never had his arm cut so the body in the morgue wasn't his. 

I'm not a fan of the Partridge being alive theory because it flies in the face of Cho, Lisbon, Jane and a host of others missing that it was not him and it was faked and before Lisbon went in the house, it would assume that she would be the one to find him and not another group of cops. BUT this is suspicious and might be the hidden clue.

On a side note Partridge said in the first episodes that RJ drew the face with 3 fingers. I know a face is small but the person painting on Lisbons face is kind of doodling with a finger.

I have so many theories but not sure where they go
